Which of the following statements is accurate concerning the vibration sensing device used with the separator shown in the illustration? Illustration MO-0127

Question

Accepted Answer

The detector mechanism consists of an armature suspended on a flexure pivot and restrained from motion by a permanent magnet acting through a small air gap.

Answer

The detector is so arranged to prevent abnormal harmonic frequencies from being developed while the separator is passing through its critical speed range.

Answer

Vibration sensors are not used with centrifuges currently installed on diesel vessels due to excessive vibrations developed by the main propulsion units.

Answer

The vibration switch is sensitive to vibration in a direction horizontal to its mounting base and is normally installed low on the separator where movement is magnified.
